Patented Dec. 8, 1931 PATET oFricE HENRY W. HONEYMAN, JR OF PROVIDENCE,RHODE ISLAND WARP LOOPING MACHINE Application filed April 22,

This invention relates to means for automatically hanging loops or foldsof traveling warp over a support; and the object of this invention is toprovide a machine to which a continuous sliver or warp is fed, themachine being provided with a reciprocating warp conducting memberarranged to swing back and forth to deposit or hang the warp in folds orloops on a bar or supporting member to be subsequently transferred onthis supporting member for further treatment.

A further object of the invention is the provision of traversing meansfor advancing the warp guiding member laterally, causing the warp foldsto lie side by side along its receiving bar.

vA still further object of the invention is to provide aset of elongatedfeed rolls and providing a warp-receiving bar of a length substantiallythat of the rolls over which the warp is laid or hung in folds or loops,the warp guide memberbeing advanced along said feed rolls to lay thewarp strands side by side along the length of the bar.

WVith these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a front elevation of the machine.

Fig. 2 is an end elevation showing a portion of the frame removed.

Fig. 4 is a diagrammatic view showing a portion of the machine inperspective, and illustrating the general arrangement of parts and theoperation of the machine.

removed to present the warp for further treatment and another barpositioned to rece1 ve the next load, but my improved ma chlne serves toautomatically hang or lay the warp over the continuously running barautomaticaly during the operation of the machine; and to accomplish thisautomatic operation in a simple and effective way, I have provided amachine to which the continuous sliver or warp is fed, the machine beingheren illustrated as having a pair of reciprocatlng rolls arranged toswing back and forth over the warp receiving bar to lay or hang the warp1n folds or loops thereover, the bar being supported for ready removaltogether with the warp hung thereon for further treating the warp; andthe following is a detailed description of the present embodiment of myinvention and showing the preferred construction of machine by whichthese advantageous results may be accomplished:

With reference to the drawings, 10 designates the framework of themachine on which 1s rotatably mounted an elongated upper feed roll 11and a similar cooperating lower feed roll 12 to which the warp 13 is fedover the guide roll let and thru the traversing guide eye 15, the warpbeing led from these feed rolls down thru the oscillating fold layingrolls '16 and 17 which swing to hang the warp upon the bar 18 supportedbelow.

These rolls 16 and 17 are supported in bearings in the swinging arms 19at either end of the machine, roll 17 being pressed thru action of thespring 20 to pinch the traveling warp against its companion roll 16,which latter roll is rotated from pulley 21 on the roll 12 thru belt 22to assist in feeding the warp.

This arm 19 is hung on the roll shaft 23 and is caused to oscillate byrotation of the crank disc 24 thru connecting rod 25 which is pivoted at26 to the disc and at 27 to the oscillating arm 19. V

In order to cause the warp to advance lengthwise along the elongatedfeed rolls and have its folds 36 lie side by side along the bar 18supported on arms 33 beneath the same, I have provided a traversingscrew 28 to which the warp guide eye 15 is connected. This traversescrew has the usual pawl 29 mounted in the nut 30 mounted thereon, toenter the helical groove 31 in the screw and as the screw is rotated thepawl follows the screw and causes the nut and guide eye 20 to advancealong the feed rolls and upon arriving at the end of the screw the pawlis caused to follow the groove over into the return groove as bestillustrated in Fig. 6, to automatically reverse its direction of travelat either end of the screw, which continues to run in the samedirection.

In order to prevent this nut 30 from rotating on its screw 28, I haveprovided a guide arm 32 which engages and slides along the guide rod 35.

The machine is driven from the main roll shaft 23 thru clutch pulley 34and motion is transmitted from this shaft thru sprocket chain 37 to thetraverse screw 28 and thru sprocket chain 38 to the crank discs 24.

My improved warp-folding machine is very simple and practical inconstruction and efiective in its operation and by its use the warp maybe automatically hung in folds along the length of the bar, which barmay be readily removed with the warp thereon into any desired positionfor subsequent treat ment of the warp.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which thedevioe'is susceptible, the invention being defined and limited only bythe terms of the appended claims.
